Product Details: Healthy blood vessels, heart and bones We know that Vitamin K is essential for normal blood clotting and for building and maintaining strong, healthy bones. But latest research suggests that a special form of Vitamin K, called menaquinone-7 (K2), may play an important role in blood vessel and heart health too. By supporting healthy blood vessels, Vitamin K2 may maintain optimum blood circulation - essential for healthy heart function. And K2 is now thought to be even more helpful in contributing to the normal structure of bone than Vitamin K1. K2 is highly bioavailable and bioactive, and remains in the blood for longer than K1. This means the body"s reserves can be built up and tissues supplied continuously. And unlike Vitamin K1, Vitamin K2 is safe to take with blood thinning medication, at the suggested daily intake. An excellent food source of Vitamin K2 is natto (fermented soya beans) - not a common Western dietary choice. Cheese and curd are also good sources, but people following a heart-health diet are recommended to reduce such foods in their diet, and they"re usually high in salt. Higher Nature"s Vitamin K2 is sourced from natto. The optimal daily intake as determined by research is 45mg - more is not necessary. Suggested intake: Take one tablet a day. Bullet points: Vegetarian Gluten Free Sugar Free Ingredients: One tablet typically provides: 45g Vitamin K2 (menaquinone-7). Dairy free.
